| Population justification: The population is estimated at 612-6,120 individuals (1-10 individuals/km2 x 612 km2 [45% EOO]), i.e. may fall in band 250-999 mature individuals. This equates to 375-1,499 individuals in total, rounded here to 350-1,500 individuals. No density estimates for congeners, but density range is up to the lower quartile of 42 estimates for 18 Apalis, Camaroptera, Calamonestes and Eremomela spp. in BirdLife Population Density Spreadsheet. According to Mills (2010) it occurs over a length of c.370 km of scarp c.10 km wide, giving it a range size of c. 3700 km2, and it can be common in secondary growth. Mills (2010) therefore concluded that the population is almost certainly greater than 1,000 individuals. | ||||
| Trend justification: The population is suspected to be in decline at a moderate rate, owing to the continued clearance and burning of its habitats for subsistence agriculture. | ||||
